2. In all places of the Earth, save exactly under the Poles, the Days and Nights are of equal length (viz. 12 hours each) when the Sun is in the equinoctial.
3. Those who live under the equinoctial, have the days and nights of equal lengths at all times of the year.
4. In all places between the equinoctial and the Poles, the days and nights are never equal, but when the Sun is in the equinoctial points ♈ and ♎.
5. The nearer any place is to the equator, the less is the difference between the length of the artificial days and nights in the said place; and the more remote the greater.
6. To all the inhabitants lying under the same parallel of latitudes the days and nights are of equal lengths, and that at all times of the year.
7. The Sun is vertical twice a year to all places between the tropics; to those under the tropics, once a year; but never any where else.
8. In all places between the Polar Circles, and the Poles, the Sun appears some number of days without setting; and at the opposite time of the year he is for the same length of time without rising; and the nearer unto, or further remote from the Pole, those places are, the longer or shorter is the Sun’s continued presence or absence from the Pole.
9. In all places lying exactly under the Polar Circles, the Sun, when he is in the nearest tropic, appears 24 hours without setting; and when he is in the contrary tropic, he is for the same length of time, without rising; but at all other times of the year, he rises and sets there, as in other places.
10. In all places lying in the (Northern/Southern) hemisphere, the longest day and shortest night, is when the Sun is in the (Northern/Southern) tropic, and on the contrary.
